A. RJ45 connector panels provide connections to monitor signals from I/O modules.
- Each connector is linked to one I/O module on the carrier board.
- Analog I/O modules (channels 0-15) will use only the first column of connectors.
- Digital I/O modules will use both columns:
- Channels 0-15 in the first column
- Channels 16-31 on the second column
- See the RJ45 Connectors section in the IO Connectors page for detailed information.
B. Power switch and LED indicator.
C. 4 SFP ports (for MuSE or device interconnection) and status LEDs for each channel (LED 0 = channel 0):
- Blinking green: an SFP module is plugged into the port and the bitstream is using Aurora for this channel
- Continuous green: an SFP module is plugged into the port and the bitstream is not using Aurora for this channel
- Blinking red: rx_loss is 1
- Continuous red: tx_fault is 1 (these are SFP status signals)
- OFF: no module plugged into the port and no Aurora present in the bitstream for this channel
D. Synchronization connectors (fiber optic and audio) and a series of four LEDs on the front panel display the device status.
LED | Power On | After Load & During Execution | After Reset |
|---|---|---|---|
Tx | Off | Green** | Off |
Rx | Off | Green** | Off |
M/S | Default* | Orange = Slave | Green |
PWR | Green | Green | Green |
*The color of the LED on power-on depends on the default FPGA configuration:
- When the FPGA board is programmed in Slave synchronization mode, the LED will be orange.
- When it is programmed in Master mode, the LED will be green.
**Tx and Rx provide synchronization information.
- When transmitting the synchronization signal, the Tx LED will be green.
- When receiving the synchronization signal, the Rx LED will be green.
E. RJ45 connectors with mini-BNC terminals for monitoring.
- RJ45 cables connect from a channel on an RJ45 panel (A) to one of the four RJ45 monitoring connectors (D).
- Mini-BNC connectors allow for quick cable connections to monitoring devices (such as an oscilloscope)
- See OP5705XG Connecting Monitoring Devices for details.
F. USB JTAG for Artix7 FPGA (for OPAL-RT technicians’ use only).
